Scenario
An update has been released to the Signature 365 Outlook add-in, and you have been advised by Symprex that the Signature 365 add-in must be manually updated to take advantage of the improvements it contains.
Information
Whilst the Outlook add-in will in most cases self-update when installed from either the Microsoft 365 integrated apps deployment, or when manually installed using the manifest XML, there are occasions where a major update to the add-in will require a redeployment to allow the update to occur.
In these situations, information will be sent out from the Symprex social media feeds, or by an email update to customers. There are circumstances where a member of the support team will request that this be completed.
Solution
The update process will differ depending on how the add-in has been installed for your users.
Log on to the Microsoft 365 Admin center as a Global Administrator.
Go to Settings > Integrated apps to open the Integrated apps page. The Signature 365 app will show Updates pending as its Status.
Click on the app name. In the flyout on the right-hand side of the screen, select the "Know more and update" button.
The next page will detail the changes and any new capabilites the app can perform.
Review the next screen, and select the "Accept and update" button.
Wait for the update process to complete - once this is finished, click the "Done" button.
Important
The add-in may not be available to all users immediately. The deployment usually only takes a few minutes but can take up to 6 hours according to Microsoft. For some users, the add-in may not be available until Outlook has been restarted.
